The big drawback is how little the grid pay you back, you really need a battery to make up for it.
Sodium ion batteries will be a real gamechanger in this department.
Ive been looking at building a bank out of 18650 batteries from e-bike packs, i can find these easily and cheap but would take a bid to build.
After seeing Louis Rossmann's experiences with cheap e-bike batteries, I would NOT want those anywhere near where I sleep...
The ones ive pulled apart however are from flagship bike brands and have high quality samsung or panasonic cells inside.
Sure there is a fire risk with any lithium battery, this can be mitigated by managing the charge voltages and keeping the float level down below maximum charge level which also extends the life of the battery.
Lots of ebikes and scooters, etc are moving to lithium iron phosphate chemistry which has a lower fire risk.
In addition to that, I plan to keep the battery in the corner of my garage which is built out of concrete blocks away from any combustible material.
I may end up going with prismitac cells or some rackmount UPS batteries anyway, there are a ton of options out there these days.

Oh for a government here to actually realise the potential of getting distributed generation onboard for addressing grid demand.
Only problem is the costs that will be passed onto the consumers.
One more incentive to upgrade to solar anyway i guess.
